Kamfora

Kamfora is a white, waxy, flammable solid with a strong aromatic odor. It is a crystalline terpene or terpenoid, specifically a bicyclic monoterpene with the chemical formula C10H16O. It is naturally produced by the camphor tree (Cinnamomum camphora) and other related species.

Historically, kamfora has been used in traditional medicine for various ailments, including as an expectorant, decongestant, and topical analgesic. Its strong scent is also believed to have repellent properties against insects. In religious ceremonies, it has been burned as incense.

Chemically, kamfora can be extracted from the wood of the camphor tree or synthesized from turpentine. It is soluble in organic solvents like ethanol and ether, but poorly soluble in water. Its flammability and distinctive smell are key characteristics.

In modern applications, kamfora is used in the production of plastics, particularly celluloid, and as a moth repellent. It is also an ingredient in some liniments and balms due to its counterirritant properties. However, due to potential toxicity if ingested, its use in internal medications has largely been discontinued in many regions, and its use in over-the-counter products is often regulated. When handled, proper ventilation is recommended due to its strong vapor.
